Base to acid: R_B/A = R_B/R_A = (Fe₂O₃ + CaO + MgO + Na₂O + K₂O)/(SiO₂ + Al₂O₃ + TiO₂).

Base to acid: R_B/A+P = (Fe₂O₃ + CaO + MgO + Na₂O + K₂O + P₂O₅)/(SiO₂ + Al₂O₃ + TiO₂).

Fouling index: F_u = R_B/A(Na₂O + K₂O).

Thermal conductivity: λ = 0.773 lg R_B/A+P + 0.673.

Slag viscosity index: S_R = SiO₂ × 100/(SiO₂ + Fe₂O₃ + CaO + MgO).
